If you change these software settings, you must change your hardware
settings to match. Refer to Appendix A, Hardware Configuration, for
more information on changing these settings.
Exiting IBCONF
After you have made all your changes, you can exit
IBCONF
by pressing
<F9> or <Escape>. The program asks if you want to save the changes to
the disk before exiting. Typing a
y
(yes) response causes the changes to be
written to the file on disk.
Before exiting, the program checks for situations that can cause problems,
such as the following:
•
Is there a GPIB addressing conflict between a device and its access
board?
•
Are GPIB boards not present in the host machine at the specified
address?
•
Are timeouts disabled on a device or board?
If any of these situations are found, you are notified and given the option of
re-entering or exiting
IBCONF
.
